We’ve been having his issue with our OnDemand instance (2.0.10) for a while and haven’t been able to find a solution yet. We’ve tried a few things on our end without luck.
Basically, the dashboard seems to take a very long time to load:
The actual authentication part does not seem to be the issue as that happens within a matter of seconds. This was an issue back when we were using LDAP auth and also now with ADFS. It just seems to sit there forever waiting to initialize the dashboard. Common for it to take 30 seconds to a minute or more.
I saw a topic in OnDemand’s known issues regarding slow dashboard performance due to ERB logic. The only thing that’s really changed is adding interactive apps such as Jupyter and JupyterLab. To test I backed those up, removed them from the apps directory, restarted OnDemand and the slowness issue is still there.
The only thing that we notice a difference with is that newer accounts tend to take less time to load than established accounts. Meaning if someone is a member of multiple groups in AD, that seems to tack on the amount of time it takes to load the dashboard. Not sure why this occurs though/relevance or what is happening in the background.
Clicking on Job Composer, etc once you’re in yields the same issue:
We’ve been stuck on this one for quite some time. Any ideas are really appreciated.
